ScoutForce has a "web-based mobile app" which means it's not actually an app you need to download from the app store. You can access easily by opening up your internet browser and typing in the web address: apps.scoutforce.com. This will take you to the ScoutForce login screen. From here you can save the website to your home screen which will allow you to access it much quicker.
Note: the mobile app is an abbreviated version of ScoutForce which means it doesn't have as many features as the full site version. That's because of the smaller screen on a phone or tablet. However, you can easily access the full site version on your smartphone or tablet by clicking the "bolt" icon at the top of the page after you log in to the mobile app.
